IP Video year-over-year, unique viewers, total streams, streams per viewer and time per viewer were up, led by 17 percent growth in total streams during November 2009, according to the latest market study by Nielsen.
There were 138.4 million unique viewers of online video that month. They watched 11.2 billion video streams, or about 81 streams per viewer. Viewers spent 200 minutes per viewer, on average, watching online video streams.
One notable example of this amazing growth -- retaining its number one rank, by far -- Youtube served up 6,753,100,000 total video streams in November 2009.
Nielsen combines patented panel and census research methodologies to provide an accurate count of viewing activity and engagement along with in-depth demographic reporting.
Online video viewing is tracked according to video player, which can be used on site or embedded elsewhere on the Web. For example, if a "Saturday Night Live" clip from NBC.com is embedded on a personal blog, that video would be attributed to NBC because of the NBC video player.
A unique viewer is anyone who viewed a full episode, part of an episode or a program clip during the month. A stream is a program segment. Note, Nielsen VideoCensus measurement does not include video advertising.
Effective with June 2009 data reporting, Nielsen has made several enhancements to the VideoCensus service, including a panel that is eight times larger, more granular reporting and improved accuracy and representativeness.
For some sites, trending of previously-reported data with current results may show percentage differences attributable to these product enhancements and should only be compared directionally.
